Abstract: A computer implemented method, a computer system, and computer code stored on tangible, non-transient media, for determining bandwidth of a page load for a specific feature associated with the page. Network traffic associated with requests of a loading of a page to be displayed on a device is monitored. Requests of the loaded page are assigned to an associated function of the page. A set parameters associated with loading of each of the plural features is determined and a scoring function is applied to each set of parameters to determine a raw score. The raw score is normalized into a performance score for the corresponding feature in accordance with a standard total performance score for the page.
